Select the correct statements about bicyclo[3.2.1]octane.

AC-8 is the one-carbon bridge
BC-1 and C-5 are the bridgehead carbons
CC-6 and C-7 belong to the three-carbon bridge
DIts molecular formula is $C X_{8} H X_{16}$

Answer: A, B

Numbering goes C-1 (bridgehead), C-2 to C-4 (3-carbon bridge), C-5 (bridgehead), C-6 and C-7 (2-carbon bridge), C-8 (1-carbon bridge); so the first two statements are true and the third is false. The formula is

C X_{8} H X_{14}

(bicyclic alkane), not

C X_{8} H X_{16}

.
